My company-which-shall-go-unnamed initially said that they will reimburse returning teachers who book their vacation flights. As in, teachers who renew their contracts will be paid back for their flight costs.

Now they are saying that the flight reimbursement is pro-rated. For example if you take your vacation 6 months into your contract they will only pay for half your flight. This was not mentioned prior (to my knowledge).

You couldn't wait and take your vacation at the end of your contract unless you wanted to not renew with the company.

In this situation, if it turns out that what they are doing is wrong, how does one go about righting the situation? Do I go to the MoL or do I get a lawyer or what? What are the success rates of this type of thing?

I'm aware of the pratfalls of working with these type of companies so this thread doesn't need to be a big CJ about how bad they are. I just want to know if what they did is on the level and if not how I can fight it?

I assume you must have sorted out your flight reimbursement problem as you are currently considering DYI projects instead of spending the cash on a lawyer.

You assumed incorrectly. What you presented was a false dichotomy of sorts. And not in the least bit relevant to the discussion. Of course a person could afford a lawyer and materials for a DIY project. While there is a finite limit of how much money a person can possess, that limit would certainly be enough to obtain legal council, lumber, and nails.

Kudos to you for your contribution of pedantic jostling; think of it as adding a bit of color to an otherwise dull exchange of information. (I give you an A+, well written and a much more impressive response than just writing ...'yawn')
